Given directed line segment with endpoints A(-3, 1) and B(5, 13), what is the coordinate that partitions the line segment into a ratio of 1:3?
A(4, –1)
B(–1, 4)
C(–⅓, 5)
D(5, –⅓)
Answer:
B(–1, 4)
Step-by-step explanation:
We want to find a point P(x,y).
Since it is on the directed line segment AB in the ratio 1:3, it means that:
[tex]P - A = \frac{1}{1+3}(B-A)[/tex]
So
[tex]P - A = \frac{1}{4}(B-A)[/tex]
We apply this to both the x-coordinate and y-coordinate of P.
x-coordinate:
x-coordinate of A: -3
x-coordinate of B: 5
x-coordinate of P: x
So
[tex]P - A = \frac{1}{4}(B-A)[/tex]
[tex]x - (-3) = \frac{1}{4}(5 - (-3))[/tex]
[tex]x + 3 = \frac{1}{4} \times 8[/tex]
[tex]x + 3 = 2[/tex]
[tex]x = -1[/tex]
y-coordinate:
y-coordinate of A: 1
y-coordinate of B: 13
y-coordinate of P: y
So
[tex]P - A = \frac{1}{4}(B-A)[/tex]
[tex]y - 1 = \frac{1}{4}(13 - 1)[/tex]
[tex]y - 1 = \frac{1}{4} \times 12[/tex]
[tex]y - 1 = 3[/tex]
[tex]y = 4[/tex]
So the correct answer is given by option B.
X + (x + 1) + (x + 2) = 264

What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that a writer was paid $24,000 for a 4,000-word article.
Assume that the writer was paid $[x] per word. Then, we can write -
4000x = 24000
[x] = 24000/4000
[x] = 24/4
[x] = 6
Therefore, the writer was paid $6 per word.

Dalton made b batches of a dozen muffins. He divided the muffins into 3 equal cans. Now, he has 96 muffins in each can. How many batches of a dozen muffins did Dalton bake?
b × 12 ÷ 3 = 96
b ÷ 12 × 3 = 96
b ÷ 12 ÷ 3 = 96
b × 12 × 3 = 96
Answer:
Option A: b × 12 ÷ 3 = 96 is the correct answer.
Step-by-step explanation:
Given that:
Batches of muffins made by Dalton = b
Dozen muffins means = b * 12
As he divided the muffins into 3 equal cans, then we will divide it by 3
[tex]\frac{b*12}{3}[/tex]
As there are 96 muffins in each can, thus
[tex]\frac{b*12}{3}=96[/tex]
Hence,
Option A: b × 12 ÷ 3 = 96 is the correct answer.

Abe, Bob, Carl, Dan and Earl are going to stand in line for a photo. What is the probability that the boys will stand in alphabetical order from left to right in the picture
Answer:
0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture
Step-by-step explanation:
Probability:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
Arrangments of x elements:
The total number of arrangments of x elements is given by:
[tex]A_{x} = x![/tex]
Desired outcomes:
Standing in alphabetical order, so only 1 possible outcome, which means that [tex]D = 1[/tex]
Total outcomes:
Arrangments of 5 people, so
[tex]T = A_{5} = 5! = 120[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{120} = 0.0083[/tex]
0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

Remember [tex]c^{2}[/tex] should always be the hypotenuse or the longest side.
[tex]112^{2}+b^{2}=113^{2}[/tex] ---> evaluate the exponents
